Pregnant women are diagnosed with anemia when Hb is less than 11g/dl.Although there are many causes of anemia, in pregnant women, the most common cause of anemia is iron deficiency. This is the result of the body not being supplied with enough iron needed to make hemoglobin, a protein-based component responsible for the main function of red blood cells.
Women of reproductive age are inherently subject to a very high risk of anemia, during pregnancy, the need for iron increases many times to supply the fetus. At this time, anemia is further promoted.
Therefore, women who are malnourished before pregnancy with an unscientific diet, do not get proper rest during pregnancy will cause anemia even more.
